How to register your own Printful OAuth app

Create a Public App with Printful and connect it to Tenklo

This guide shows you how to create a Public App in the Printful Developer Portal and obtain your OAuth credentials (client ID and client secret). These are required to let your users grant your app access to their Printful store via the Public App installation flow.

Open the Developer Portal

  1. Go to the Printful Developer Portal and sign in with your Printful account.
  2. Click Create an app, then fill in the required information.
  3. In Redirection Domains, add api.tenklo.dev.
  4. For App URL, add https://api.tenklo.dev. This field is not used by Tenklo but is required to create the app.
  5. Select the scopes for your app (you don't need to configure these in Tenklo after selecting them here).
  6. Submit the form to create your application. Once created, your Client ID and Client Secret will be displayed—save these; you will need them when configuring the integration in Tenklo.
